FEED MIXER.

Application filed April 6, 1928, Serial No. 267,991. Renewed March 20, 1929.

This invention relates to a feed mixer, the general object of the invention being to provide means for mixing molasses or the like with ground material in such a manner as to secure a uniform homogeneous mass free of lumps, and in which the molasses is so mixed with the ground material that the finished product will not be sticky.

Another object of the invention is to provide an arrangement of beaters which revolve in a cylindrical container and which act to counteract the action of centrifugal force and keep the materials being mixed adjacent the center of the cylinder and also act to move the materials toward the rear end of the cylinder, the rearmost beater being so arranged that it tends to cause the material at the rear end of the cylinder to pass through a discharge port in the rear end of the cylinder.

Another object of the invention is to form the shaft which carries the beater with a bore in its front end into which the molasses or other liquid is forced by gravity or pressure, with ports in theshaft through which the molasses escapes into the cylinder so that the molasses is sprayed upon the ground material in the front part of the (1 cylinder.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims.

In describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is an elevation of the device.

Figure 2 is a view of the front end thereof.

Figure 3 is a view of the rear end of the cylinder.

Figure 4 is a view of one of the second set of beaters.

Figure 5 is a view of one of the first set of beaters.

Figure 6 is a longitudinal sectional view through the device.

Figure 7 is a section' on line 7-7 of Fig. ure 6.

Figure 8 is a section on line 8-8 of Figure 6.

' In these views, the numeral 1 indicates a cylinder which is held between the ends 2 by the tie rods 3, the ends being fastened to the supporting members 4. A shaft 5 passes through the cylinder and its ends, the front end of the shaft being journaled in the boss 6 which is formed with the front end of the cylinder, suitable anti-friction means 7 being provided for this end of the shaft. The other end of the shaft is journaled in the boss 8 formed on the opposite end piece and in the upright 9 attached to the supporting members. A pulley 10 is fastened to the rear end of the shaft between the end of the cylinder and the upright 9.

Suitable anti-friction means 11 are also provided for the rear end of the shaft.

The front end of the shaft is formed with a bore 12 which terminates adjacent the center of the shaft and ports 13 are formed in the shaft for placing the bore in communication with the front part of the cylinder. Molasses or the like is forced into the bore by gravity or pressure through the pipes 14., one of which is connected with the outer end of the bore through the packing gland 15, a spider 16, connected with the boss 6, supporting the pipes 14 adjacent the cylin- A hopper 17 is connected with the front end of the cylinder by the chute 18 and a discharge spout 19 is formed at the rear end of the cylinder and extends to one side thereof, as shown in Figure 8. A by-pass chute 20 connects the hopper with this spout so that by manipulating the gate 21 in the hopper, the ground material from the hopper can be caused to pass through the chute 18 into the front end of the cylinder or through the chute 20 into the spout. In this latter case, of course, the ground material will not pass into the cylinder.

A set of heaters 22 is fastened to the bored part of the shaft, each beater 22 having its free end twisted so that its extremity'lies at rightangles to the stem of the beater and a blade 23 is detachably connected to the extremity of each beater so that the blade can be renewed when worn or detached for sharpening purposes. As shown, the blade of each beater 22 extends parallel with the axis of the cylinder and by twisting the outer ends of the boaters, as shown in Figure 5, a hook-like part is formed on each beater which tends to move the material from the'walls of the cylinder toward the center thereof as the shaft and toward the rear end of the cylinder.

heaters are being revolved. Thus the beaters tend to counteract the action of centrifugal force which tends to throw the material against the walls of the cylinder and the hook-shaped parts of these heaters also tend to move the material toward the rear end of the cylinder.

A second set of heaters 24 is arranged on the shaft in rear of the first set and each of these heaters has its outer end twisted at a 45 angle, with a blade 23' detachahly fastened to the extremity of this twisted por tion. Each of these heaters 24 is provided with an extension or tail part 25 which is oppositely arranged from the main portion of the heater and these heaters also act to I, counteract the action of centrifugal force on the feed and move the feed from the sides of the cylinder toward the center thereof and these heaters also act to move the feed The tail parts 25 act, with ,the rest of the heaters, to thoroughly mix the materials in the cylinder together.

A single heater 26, made like each heater 24, but having its twisted portion extending in an opposite direction from the twisted part of the heater 24, is placed on the shaft at the rear of the cylinder and this heater tends to check the rearward movement of the material and to force the material into the discharge spout 19. The drawings show that part of the shaft within the cylinder as of square shape in cross section, with all of the heaters provided with square eyes 27 which fit over the shaft, but it will, of course, he understood that the shaft may he made of circular shape in cross section and the heaters may be attached thereto in any desired manner.

From the foregoing it will be seen that when the device is in operation, the shaft being driven from any suitable power plant by a belt passing over the pulley 10, the ground material will pass from the hopper through the chute 18 into the front part of the cylinder and the molasses or other liquid to be mixed with the material will be sprayed into the cylinder from the bore 12 through the ports 13. The first set of heaters 22 will act to mix the ground material with the molasses, as the material will be thrown toward the walls of the cylinder by centrifugal force and the heaters will move the material back toward the center of the cylinder, the blades on the heaters scraping the molasses and the ground material sticking to the walls of the cylinder therefrom, so that the molasses is mixed with the ground material.

As the feed moves toward the rear of the cylinder, it will he engaged by the second set of heaters 24 and their tails 25 so that the ground material and the molasses is more thoroughly mixed together as the feed is being agitated hy the action of the heaters. The blades on these heaters also scrape the material off the walls of the cylinder, while the heaters move the material toward the center of the cylinder. At the same time the heaters move the mass toward the rear end of the cylinder where it is engaged by the heater 26 which checks this rearward movement and forces the mass into the discharge spout 19.

Thus the molasses and ground material are thoroughly mixed together and with this device, it is not necessary to heat the molasses, though, of course, it may be heated if desired. By introducing the molasses at the center of the mass of ground material at the front of the cylinder, it is thoroughly mixed with the material by the first set of heaters and this mixing action is carried on by the second set of heaters so that the feed is discharged at the end of the cylinder in a uniform homogeneous mass, free of lumps and the molasses is so thoroughly mixed with the ground material that the feed will not he sticky. As before stated, by moving the gate 21 from one position to another, the ground material can he directed into the discharge spout without passing through the cylinder.

It is thought from the foregoing description that the advantages and novel features of my invention will be readily apparent.

It is to he understood that I may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall wlthin the scope of the appended claims.
